Tether, on Polygon

USDT0 on Polygon is the USDT0 representation of USDT within the USDT0 Network. It keeps one unified USDT across supported chains instead of a separate bridged version with isolated liquidity. For users on Polygon, USDT0 works as the USDT asset available through the USDT0 system.

Transfers to and from Polygon are secured by LayerZero, the interoperability protocol behind USDT0, and by the USDT0 Attestation System. The Attestation System verifies every transfer through independent attestation before it finalizes. Each message needs sign-off from the Core Attestation Set, a 3-of-3 signer group of USDT0, LayerZero, and Canary. No single verifier can approve a transfer on its own. USDT0 moves with a burn-and-mint model and 1:1 backing: no wrapped tokens, no external bridges.

Moving USDT0 between Polygon and any other USDT0 Network chain has no protocol fee (0 bps). You only pay network gas on the source and destination chains. When the other side is a Legacy Mesh chain (native USDT on Solana, TON, Tron, and Celo), the transfer routes through the Legacy Mesh and costs 0.03% (3 bps), paid in USDT.

The Polygon USDT contract address is 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. This is the contract for the token you receive when you bridge USDT to Polygon through USDT0. Double-check the full address before sending funds.

On Polygon, the USDT0 transfer widget supports MetaMask, Rabby, and other EVM browser wallets, Coinbase Smart Wallet, or any wallet connected through WalletConnect. Add the Polygon network in your wallet, then import the contract address above if your balance does not appear automatically.

Yes: you can bridge Tether Gold to Polygon as XAUT0, alongside USDT. XAUT0 uses the same burn-and-mint model as USDT0, with 1:1 backing. Select XAUT in the bridge to move it to or from Polygon.

XAUT0 on Polygon is the representation of Tether Gold (XAUT) within the USDT0 Network. Every XAUT0 token corresponds to Tether Gold, where 1 token = 1 troy ounce of physical gold. Holding XAUT0 on Polygon is equivalent to holding Tether Gold within the USDT0 system.
